Laminating device and method for laminating at least one layer stack

Laminating device for laminating, by means of at least one of pressure or heat, at least one layer stack having at least one plate-like workpiece and at least one layer that is also effective as an adhesive layer, the laminating device comprising:

• a lower part,
• an upper part which is connectable in gas-tight manner to the lower part,
• an openable and closable working chamber formed between the lower part and the upper part and configured for receiving the at least one layer stack when laminating,
• a pressure plate movable within the working chamber between the upper part and the lower part along a pressing axis,
• at least one sealing frame arranged between the lower part and the upper part,
• a plurality of mutually separable pressure chambers that are operable and arranged in the working chamber,
• wherein a plurality of mutually spaced clamping positions is arranged in a direction of the pressing axis and is configured for fixably arranging at least one flexible gas-tight element at the clamping positions and wherein, by application or non-application of pressure or negative pressure to the at least one flexible gas-tight element, the movable pressure plate is movable,
• wherein the at least one flexible gas-tight element divides the working chamber into a first pressure chamber of the mutually separable pressure chambers, the first pressure chamber being located above the at least one flexible gas-tight element, and a second pressure chamber of the mutually separable pressure chambers, the second pressure chamber being located below the at least one flexible gas-tight element and the movable pressure plate being arranged in the second pressure chamber, wherein movement of the movable pressure plate is effected due to a difference of pressure between the first pressure chamber and the second pressure chamber,
• wherein the at least one sealing frame includes at least one intermediate frame provided separately from the lower part and from the upper part,
• wherein the clamping positions are arranged at least between the at least one intermediate frame and the upper part, and between the at least one intermediate frame and the lower part,
• wherein the at least one flexible gas-tight element is clamped into a gap above the at least one intermediate frame, and a further flexible gas-tight element configured to serve as a membrane is clampable into a gap below the at least one flexible gas-tight element,
• wherein the laminating device is configured for operating with or without the membrane, and
• wherein, when the further flexible gas-tight element is clamped in place, at least three pressure chambers are provided including the first pressure chamber, the second pressure chamber, and a third pressure chamber, the first pressure chamber and the second pressure chamber being separated by the flexible gas-tight element and the second pressure chamber and the third pressure chamber being separated by the further flexible gas-tight element.
